I know the power PC architecture isn't officially supported, but I have hacked Xcode (4.1.1) and the iPhone SDK (2.1 ) to work with my G5, and have been using it for quite some time.

SIO2 compiles perfectly with this, but when I do final linking, it can't find _sio2Shutdown and _sio2Init . These functions are in the libsio_sim.a library. Could the source code to that library be provided, or alternatively, could you make the powerPC compiled version of that lib available?I know you won't want to officially distribute it, and I don't expect you to support PPC just for me!
